Application filed September 27, 1818. Serial No. 792,104.

To all whom it may concern Be it known that I, Gnonon W. BLAKE, a citizen of the United States of America, residing at Wgandotte, in the county of Wayne and tate of Michigan; have invented certain new and, useful Improvements in Pourin -Spouts, of which the following is a speci ication, reference being had therein to the accompanying drawings.

This invention relates to a pouring spout for a package and more especially to an arrangement thereof whereby the contents of a package may be readily discharged as it is needed and the package resealed with out the use of implements, the spout forming a closure for a delivery opening of the package, and also roviding a discharge trough that is best a apted to prevent lodgment of material passing thereover.

0 The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a View of an upper portion of a package provided with 5 a spout that embodies features of the invention; Fig. 2 is an enlarged view of a transverse section through the upper portion of the spout and receptacle, showing the spout in its closed position; Fig. 3 is a simig lar view showing the spout in open position; Fig. 4 is a view in detail of the opening in the receptacle, with a section line II--II' thereon that indicates the point where the views shown by Figs. 2 and 3 are taken.

5 Figs. 5 and 6 are views in section and in detail, enlarged, showin the adaptation of a spout to a different orm of receptacle; Fig. 7 is a plan view in detail of the modification; and Fig. 8 is a view in perspective )of the spout removed. p

Referring to the drawings, a receptacle 1 has a substantially triangular opening with depending apex as indicated at 2 in Fig. 4, an inset, flange .3 being preferably formed 3 around the opening, one section of which has a longitudinal hinge slot 4. The hinge portion of the flange is interrupted to form a pouring gap 5 at the lower apex of the opening 2. A V shaped pouring trough has lone side 6, a cover side that conforms to the contour of the shoulder formed by the inset flange 3 so as to rest in the recess thus made in overlappin relation to the flange.-

A suitably arrange hinge tongue 7 of any i preferred shape engages the slot 4 whereby the side 6 may be swiuig in and out ofcontact with the side of the receptacle. Preferably the side6 isformed to constitute a substantially flush continuation of the side of the receptacle on which it rests. Along the margin of the side 6 opposite that on which the tongue 7 is formed, the side is mtolded against itself so that the resultant tongue 8 bears against the flange while an inner portion 9 forms a free side that'corresponds 1n shape substantially to the outllne oi the opening 2, projects when the spout 1s closed, into the interior of the receptacle. At its inner edge a marginal flange 10 acts as a lock to prevent withdrawal from the casing. The side 9 is conoidal wlth the hinge pivot as its axis so that it 1s. always in rictional engagement with the contiguous margin of the opening. In order that the spout may be locked when closed, the inset bend or groove 12 is formed at the angle between the flange 8 and side 9 into WhlCh the margin of the body snaps when the spout is closed. The upper mar- 'n 13 of the side 9 is also curvilinear with its center of motion at the lower corner of the trough so that it bears upwardly against the upper margin 14 of the opening. A finger pull 15 is formed on the side 6 and may if desired bearranged to bend over the upper edge of the receptacle 1 so that when the package is ready for shipment a label may be pasted over the closed spout and may be readily turned by inserting afinger nail under thefinger pull 15 and'drawmg the spout out or the finger pull may extend laterally.

In Figs. 5, 6 and 7 modifications of the invention whereby the spout may be made adaptable to a flat walled receptacle, are shown. In such construction, the cover side is merely made to conform to the wall against which it closes.

In operation the spout when closed forms a hermetrical seal for the package. When open it provides a V shaped trough through which granular substances readily pass. The interruption of the slot-ted flange of the opening at the apex of the latter effectively prevents the lodgment of anything in the spout when ,the latter is being moved back into closed position, such material falling back into the body of the receptacle.

Obviously, changes in the-details of con struction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts. p

What I claim is z- 1. The combination with a receptacle hav-' OHIIIW' o enin the cover side bein ada ted to overlap the margins of the opening when the spout is in closed position.

2. The, combination with a receptacle having a triangular pouring opening in the receptacle, with inset margins around the opening and a hinge slot in the receptacle along one inset margin of a two sided pouringspout with a cover side provided'with a hinged member engaging the slot and with:

margins that overla the insetmargins oi the opening, and a side extending from the 1,1 iaeae L free margin of the hinge side in slidin engagement with the contiguous margin 0 the opening, and having a longitudinal depression adjacent the hinge side the margins of p the receptacle "adjacent the latter side being adaptedto engage the lon itudinal de pression in said side adjacent t e overlying flange of the cover side. I

3. A pouring spout for a receptaclelhaving a triangular opening, comprislng a cover side adapted to close over the opening and hinged to the receptacle along one side thereon, and a free side formed integrally along the free edge of thecover side, with a flange on the other edge thereof limiting the outward movement of the spout in-the opening, the free side being indented along the line of its connection with the coverside and being adapted to yieldingly engage and hold the side of the opening in said indentation when the spout is in closed position.

In testimony whereof ll afixiny signature in presence o f two witnesses.
